Definitions

  • the present invention relates to a closure cap for a container, and in particular to a ring structure for engagement with a container neck of the container.
  • closure caps are provided with a tamper-evident band, which is secured to the closure cap.
  • the tamper-evident band gives an indication that the container has been initially opened or tampering has occurred.
  • Such closure caps usually involve elaborately molded one or multiple piece caps, which frequently require a special container. The purpose in using such a closure cap is to insure customers that the container package has remained closed in its originally filled condition prior to purchase.
  • closure caps with the tamper-evident band while useful in certain applications, have certain disadvantages in many applications including products packaged in glass or plastic containers, and more particularly hazardous products packaged in glass or plastic containers.
  • closure caps known in the art are sometimes known to “back off” or untwist from harmonic vibrations caused by road conditions or other non-standard forms of movement that can take place during transport. If sufficient “back off” takes place, the closure cap may become at least partially unsealed from its mating container. It would therefore be desirable to have a container cap with a structure that would prevent the cap from “backing off” from the container during transport.
  • typical tamper indicating closure caps permit a tamper indicating structure in the form of a ring to slide freely along the container neck once the container has been initially opened. This provides a potential distraction to the user when pouring the contents of the container. By securing the closure cap structure to the bottle neck, the user is able to concentrate on pouring the liquid while minimizing potential distraction from the ring.
  • the tamper indicating structure is often disposed inside the container cap and not visible to the user until the container is initially opened. It would be desirable to provide a ring-shaped structure that can be molded separately from the closure cap and disposed on both the inside of the cap for securement with the bottle neck and the outside of the closure cap for general indication of the container contents by color.
  • the purpose in using such a closure as described above includes the desirability to insure users that the container has remained closed in its originally filled condition prior to purchase, safeguard against contamination by a leaking container, and allow visual inspection of the general contents of the containers by providing a color coded structure on the cap indicating the general contents of the container.
  • the embodiments described herein illustrate a cap for a container comprising a cap body that includes an upper portion and a lower portion.
  • the lower portion has an outer circumferential sidewall defining a ring-positioning member.
  • the cap also has a ring that includes an outer member selectively engaging the ring-positioning member and an inner member disposed proximate an inside surface of the lower portion.
  • the inner member has at least one tab extending inwardly and upwardly and terminating at a first edge.
  • the inner member also has at least one finger member protruding inwardly from the inner member and terminating at a second edge above the first edge of the tab.

  • a cut liner is illustrated; however, other known gaskets or molded plastic liners may be used.
  • An outer circumferential surface 38 of the upper portion 22 includes a plurality of ribs 40 disposed parallel a longitudinal axis B-B as shown in FIG. 4 .
  • the ribs 40 provide a gripping structure so that a generally consistent torque may be applied to cap body 20 when closing or opening container 30 . Regulatory requirements outline a narrow acceptable torque range.
  • the ribs 40 allow a torque wrench to “bite” the cap body 20 and exert a consistent amount of torque during assembly.
  • the ribs 40 provide a proper fit for a torque wrench when testing the torque applied to the cap body 20 during assembly by having an equal arrangement of ribs.
  • any structure for gripping the cap body 20 may be used including deeper ribs, various shaped indentations, various shaped protrusions from the outer circumferential surface 38 , or an otherwise appropriately textured surface.

  • Locating the base of the frangible connections 70 on the outer member 52 permits a more efficient vertical separation by taking advantage of the ridged cap body 20 .

  • the tabs 58 include a sufficient length and circumferential extent to apply the necessary resisting force while still maintaining the appropriate connection between inner member 54 and outer member 52 by way of frangible connections 70 .
  • fingers 62 rest on upper surface 74 of transfer bead 76 . They prevent the closure ring 50 from moving substantially further in a downward direction. In some embodiments, a substantive force may be applied to minimize the possibility of over-torquing of the sealing cap 18 with respect to the container 30 . However, in such a situation, tolerances will be particularly important.
  • the liner 34 on the underside of the upper portion 22 of the cap body 20 is adapted to prevent the user from over-torquing the cap when the cap is tightened.
